Delaware State Police troopers are investigating a single vehicle crash that sent four people to the hospital early Wednesday morning south of Camden.

The incident occurred at approximately 2:08 a.m. Wednesday as Matthew D. Givens, 21, Milford, was driving a 2011 Dodge Nitro southbound on U.S. Route 13 when for unknown reasons, the vehicle left the west side of the roadway and struck the Worship Lane street sign just south of Lochmeath Way, State Police Master Cpl. Gary Fournier said.

The Dodge continued in a southerly direction before striking a curb and becoming airborne, Fournier said. The vehicle then struck the ground with its front bumper causing it to rotate end over end, he said. The car then struck a tree on the passenger's side where it came to a stop on its roof.

Givens and his three female passengers were all transported to Bayhealth-Kent General Hospital by EMS where they were treated for non-life-threatening injuries, Fournier said. The passengers were a 23-year-old woman from Warrington, Va., a 21-year-old woman from Harrington and a 21-year-old woman from Milford.

South DuPont Highway (U.S. 13) south of Lochmeath Way was closed for approximately two hours as the crash was investigated and cleared, Fournier said. Alcohol is believed to be a factor in this incident and charges are pending.
